Answer:
The answer is -1
Explanation:
First you need to follow the PEMDAS rule.
The negative is outside the parentheses which you would distribute. The first 4 becomes negative while the second for becomes positive. The problem is then 3-0+4 which the wether you add the 4 to 0 or subtract the 3 from 0 you will still be left with 3-4. The zero is more of a distraction when simplifying.
